The DA19678-38 is a precision altitude pressure sensor, which can measure the altitude pressure in a range of 850 to 1080 mbar with 0.2 mbar resolution. It is a pressure sensor that can be used for the applications of meteorology, flight control, aviation weather forecasting, the monitoring of the altitude pressure levels in buildings, the precise measuring of temperature and the measurement of wind speed.

The DA19678-38 is based on a capacitive transducer and uses two resistors in the feedback circuit. The transducer consists of a series of quartz resonators that have been purposely vibrated. The resonance of the quartz resonators withstands the pressure imposed on it which, in turn, changes the resonance frequency of the quartz resonators. This frequency change is the signal that is used to measure the altitude pressure.

The DA19678-38 uses a highly precise voltage regulation system and variable gain amplifier (VGA) to reduce errors in the measurement process. The VGA also ensures that the signal is linear over the current temperature range and pressure range (from 800 to 1080 mbar). The signal output from the VGA is then fed into a band-pass filter to provide a highly accurate altitude pressure measurement.

The DA19678-38 also incorporates an integrator which can be used to measure the changes in altitude pressure over a period of time. The integrator can be used to calculate the altitude change over any given time period. Additionally, the signal output from the VGA can be used to calculate the altitude required to reach a certain altitude or target.

The DA19678-38 is ideal for applications that require accurate measurements over long ranges such as flight control or meteorology. The highly accurate and linear voltage regulation system of the DA19678-38 ensures that the measurements are precise over the entire range of temperatures and pressures. The integration capabilities of the sensor also make it ideal for applications like monitoring the altitude pressure of buildings.

The DA19678-38 is a robust and highly accurate pressure sensor that can be used for a wide range of applications. Its simple design and accurate measurement capabilities make it a valuable tool for applications such as meteorology, flight control, building monitoring, and precise measurement of temperatures and wind speeds.
